You’re looking for a scripter that also knows how to model, two vastly different skillsets. I suggest you look for two seperate people to do each as well as mention a more specific payment. The amount of detail on something like handcuffs is difficult to measure.
You’re looking for a scriper. Why does it has to be detailed? Do we have to add comments so you know how it works?
Also, what do you mean by how well it works. You’re the one who gave us the specifications of everything so as long as we deliver as promised then payment should be paid in full. If you mean animating the player’s hands back as if they were cuffed then please specify that as one of your functionality requirements.
